Duct Leakage Test in Richlandtown, PA

Enhance your HVAC system’s efficiency and satisfy energy regulations through precise duct leakage test in Richlandtown, PA. Our certified technicians locate and assess air leaks in ductwork to help homeowners and builders improve comfort, reduce energy consumption, and comply with state regulations.

Why Duct Leakage Test is Important In Richlandtown, PA

Across different states and municipalities, the 2015 IECC, International Energy Conservation Code regulates single-family structures, and the 2018 International Energy Conservation Code is used for multi-family structures. The change will generate several impactful implications for home builders and HVAC contractors operating statewide. A Duct Leakage Test along with the required Blower Door Test must now be conducted on any newly built or remodeled home as per the 2015 regulations. Did you know that ducts are frequently the biggest contributors to home air loss in Pennsylvania, New Jersey, and Delaware? Leaked air can raise your energy bills, strain your HVAC system, and spread insulation and dust throughout your home. This makes duct leakage test essential for both new and older homes.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To initiate a duct leakage test in Richlandtown, PA, your technician seals all supply and return registers, leaving only the main return or air handler open. A duct blaster, designed as a calibrated testing fan, is then attached to the duct system. Its purpose is to depressurize the ducts and uncover leak points.

The duct blaster system, along with a precision pressure sensor, measures airflow and highlights leaks in the ductwork without inconveniencing you at home. A duct leakage test — sometimes labeled as a duct blaster test — finds where your ducts are leaking air so you can decide on the best sealing strategy.

duct leakage test is fast, clean, and comfortable for residents throughout the process. Most tests in Richlandtown, PA require only 30 to 60 minutes, yet the upgrades can improve your home’s comfort and efficiency well into the future.

How to Measure Duct Leakage

Duct leakage is measured in cubic feet per minute (CFM) per 100 square feet of conditioned space. Your technician uses a nanometer to evaluate small pressure shifts that signal air escaping through the ducts. Understanding this number allows you to highlight problem zones, explore improvement possibilities, and confirm compliance with local energy code requirements in Richlandtown, PA.

Cost of Excessive Duct Leakage

If high utility expenses, irregular temperatures, or repeated HVAC troubles sound familiar, duct leakage might be the root cause. According to ENERGY STAR, a large portion of homes lose between 20% and 30% of conditioned air due to leaky ducts. If outdoor hot or cold air infiltrates your system, your HVAC struggles to maintain temperatures, raising energy costs and lowering comfort.

Overworked equipment also brings more system failures and higher repair expenses. Proper duct sealing helps keep your HVAC system healthy over the long run, prolonging its lifespan and lowering continued maintenance needs.

Duct leaks can also let in dust, mold spores, added moisture, and other harmful contaminants. This can increase allergy discomfort, degrade indoor air quality, and eventually cause expensive structural issues behind walls or ceilings.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires new homes to use fully sealed duct systems crafted from up-to-date, efficient materials such as mastic, foil tape, and insulation. But what if the problem areas are buried deep within the walls or ceilings?

Aerosol sealing technology (AeroSeal) helps seal hard-to-find openings within the duct system. To carry out the procedure, technicians seal off all vents except one access point. The HVAC system is isolated, and a machine is linked to the duct system. It pressurizes the ducts and releases a fine aerosolized sealant that fills small gaps and holes that traditional sealing methods cannot reach.

This method is highly effective for small to medium leaks. However, large openings may still require manual sealing with mastic and tape. Technicians run a duct leakage test before and after aerosol sealing to quantify the reduction in leakage and verify the success of the process.

Common Areas of Duct Leakage

The most common place for ducts to leak air is through the joints. Ductwork is made of multiple metal pieces pressed together using tight fittings and metal bands, but these connections are rarely airtight.

As your HVAC system heats and cools throughout the year, the ducts expand and contract. Over time, this movement shifts and loosens the joints, resulting in gaps and leaks — which is why all homes in Richlandtown, PA, new or older, benefit from duct leakage test.

Many energy auditors detect leaks by checking the duct surfaces by hand and using a small tool to measure joint gap width. If your duct system hasn’t been sealed with mastic and approved tape, there is a strong likelihood that leakage is happening.

What Is an Acceptable Amount of Duct Leakage per Energy Code?

To achieve a passing duct leakage result, your system is required to measure under 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet when it isn’t installed. For new construction, a passing duct leakage test is essential before the home can qualify for an occupancy certificate.

If your home in Richlandtown, PA doesn’t pass a duct leakage test, chances are you’re paying more for heating and cooling — and adding long-term stress to your HVAC equipment. Meeting the 3–4 CFM requirement is critical not just for code compliance, but also for defending your home’s comfort and energy performance.

Your technician will also give professional advice on resolving leakage issues to help you achieve a passing score, cut down utility bills, and boost your home’s performance.

The Duct Leakage Test Steps Explained

A duct leakage test begins by covering all ducts and registers with duct mask tape on both the supply and return sides.

After the registers are sealed, we mount the duct tester onto the unit or onto a main return.

The ducts are then depressurized to exactly 25 Pascals. Once this is achieved, the nanometer is used to read the duct leakage.
